DETAILED DESCRIPTION OF THE INVENTION

In the following, the technical solutions of the embodiments of thepresent disclosure will be clearly and completely described withreference to the drawings of the embodiments of the present disclosure.Obviously, the described embodiments are only part of embodiments of thepresent disclosure, but not all of embodiments. Based on the embodimentsof the present disclosure, all other embodiments obtained by those ofordinary skill in the art without creative efforts are intended to bewithin the protection scope of the present disclosure.

In one aspect of the disclosure, a liquid taking device is provided, asshown in FIG. 1.

FIG. 2 illustrates a schematic diagram showing a changing state of aliquid taking device while a liquid is taking. FIG. 3 illustrates aflowchart of a liquid taking method according to an embodiment of thepresent disclosure. With reference to FIG. 2 and FIG. 3, a liquid takingmethod according to an embodiment of the present disclosure may comprisethe following steps:

S01, Filling a displacement liquid into a liquid taking bottle in aliquid taking device.

In step S01, the liquid taking device used is a liquid taking device fortaking salt, mine brine. The structure of the liquid taking device isshown in FIG. 1. The liquid taking device may comprise a liquid takingbottle 1, a heavy ball 2 and a liquid taking rope 3. The liquid takingbottle 1 has a first mouth and a bottom opposite to the first mouth. Theheavy ball 2 is disposed inside the taking bottle 1. A diameter of theheavy ball 2 is larger than a diameter of the mouth of the bottle. Thereare two liquid taking ropes 3, wherein one liquid taking ropes 3 isconnected to the first mouth of the bottle, and another liquid takingropes 3 is connected to the bottom of the bottle.

The heavy ball 2 can be rolled inside the liquid taking bottle 1. Whenthe first mouth of the liquid taking bottle 1 is placed downward, theheavy ball falls into the first mouth and blocks the first mouth, suchthat the displacement liquid in the liquid taking bottle will not leakout. When the first mouth of the liquid taking bottle 1 is placedupward, the heavy ball will fall at the bottom of the bottle; and atthis point the first mouth of the bottle is opened, such that the brineunder the ground will enter the liquid taking bottle 1 and thedisplacement liquid in the liquid taking bottle 1 is displaced.

In some embodiments, the liquid taking bottle 1 can be raised, lowered,or turned over under the cooperation of the two liquid taking ropes 3.When one liquid taking rope 3 is loosened and another liquid taking rope3 hangs the liquid taking bottle 1, the liquid taking bottle 1 will risewith the rising of another liquid taking rope 3, and the liquid takingbottle 1 will also fall with the falling of the other liquid taking rope3. In the ease that the two liquid taking ropes 3 are tensioned tosuspend the liquid taking bottle 1 at the same time, when one liquidtaking rope 3 does not move while another liquid taking rope 3 isrising, the portion of the liquid taking bottle 1 connected with therising liquid taking rope 3 can be controlled to rise. When the positionof one end of the liquid taking bottle 1 rise above the position of theother end thereof, the turn-over of the liquid taking bottle iscompleted.

In some embodiments, the displacement liquid may be a liquid having adensity smaller than that, of the brine and does not react with thebrine, such as oil. As the displacement is ongoing, only when thedensity of the displacement liquid is smaller than the density of thebrine, can the brine smoothly flow into the bottle; and only when thedisplacement liquid does not react with the brine, can the compositionof the brine being taken out not be affected. In addition, displacementliquid filled in the liquid taking bottle 1 can increase the weight ofthe bottle and facilitate the liquid taking device to be lowered to adesignated position in the brine under the action of the buoyancy of thebrine.

In some embodiments, the liquid taking device may further comprise thegravity block 4. There may be two gravity blocks 4, wherein one, gravityblocks 4 is connected between, one liquid taking rope 3 and the firstmouth of the bottle, and another gravity block 4 is connected betweenanother liquid rope 3 and the bottom of the bottle. The gravity block 4increases the weight of the liquid taking device, which can facilitatethe liquid taking device to be lowered into the brine. The gravity block4 may be positioned at the end of the liquid taking rope 3, which canfacilitate the liquid ropes 3 to adjust the relative positions of thefirst mouth and the bottom of the liquid taking bottle 1 by the aid ofthe gravity of the gravity block 4, such that the liquid taking bottle 1can be conveniently controlled.

In some embodiments, the liquid taking bottle 1 may comprise a firstbottle body and a second bottle body. The first bottle body and thesecond bottle body are arranged to opposite each other. The first bottlebody and the second bottle body have opposite ends detachably connectedwith each other by threads, and the opposite ends of the first bottlebody and the second bottle body have a diameter larger than the diameterof the heavy ball 2. That is, the first bottle body and the secondbottle body can be separated from each other. When the first bottle bodyand the second bottle body are separated, the heavy ball 2 can be filledin, and then the first bottle body is connected to the second bottlebody by thread so as to prevent the heavy ball from falling out. Inaddition. the ends of the first bottle body and the second bottle bodyfacing away from each other are respectively provided with the firstmouth and the bottom of the bottle. The mouth of the bottle is oppositeto the bottom of the bottle, which is convenient for adjusting theorientation of the first mouth of the liquid taking bottle 1, such thatthe liquid can be taken out easily.

In some embodiments, the bottom of the bottle may comprise a secondmouth and a sealing sleeve, and the sealing sleeve is arranged on thesecond mouth. When the bottom of the bottle is used as the second mouth,the structure of the first bottle body is basically the same as that ofthe second bottle body. The second bottle body can be formed byarranging a sealing sleeve to the first mouth of the first bottle body,so the second bottle body and the first bottle body can be producedtogether, thus saving production costs.

In some embodiments, the surface of the heavy ball 2 is covered with anelastic layer, and the elastic layer may be a substance havingelasticity such as rubber. With the weight of the heavy ball itself andthe hydraulic pressure in the liquid, the elastic layer on the surfaceof the gravity ball can be slightly squeezed into the first mouth of thebottle, so that the sealing effect of the heavy ball 2 is increased.

The method may further comprise step S02, controlling the, first mouthof the liquid taking bottle to face downward, and placing the liquidtaking device in the liquid to be taken.

In some embodiments, in step S02, controlling the first mouth of theliquid taking bottle 1 to face downward, and placing the liquid takingdevice in the liquid to be taken may comprise:

Placing the liquid taking bottle vertically, and extending the liquidtaking rope 3 connected to the first mouth of the bottle downward untilthe liquid taking rope 3 connected to the first mouth of the bottle isno longer stressed; the first mouth of the entire liquid taking bottle 1is facing downwards and the gravity of the entire liquid taking bottle 1is borne by the liquid taking rope 3 connected to the bottom of thebottle, that is, the liquid taking bottle 1 is suspended by the liquidtaking rope 3 connected to the bottom of the bottle.

When the liquid taking bottle 1 is suspended by the liquid taking rope 3connected to the bottom of the bottle, the two liquid taking ropes 3 arelowered at the same speed so that the force applied to the liquid takingropes 3 remains unchanged. When the liquid taking ropes are lowered to acertain degree and the liquid taking bottle 1 arrives at a position fortaking liquid, the lowering of the liquid taking bottle 1 is stopped,thereby the positioning of the liquid taking bottle 1 is completed.

The method may further comprise step S03, controlling the first mouth ofthe liquid taking bottle to face upward so that the liquid taking deviceis filled with the liquid to be taken.

In some embodiments, in step S03, controlling the first mouth of theliquid taking bottle to face upward may comprise:

Slowly lifting the liquid taking rope 3 connected to the first mouth,and the first mouth will rise with the rising of the liquid taking rope3 at this point. However, in order to ensure that the position of theliquid taking, bottle 1 remains unchanged, it is necessary to lower theother liquid taking rope 3 connected to the bottom of the bottle at thesame speed when the first mouth of the bottle starts to rise. At thispoint, the liquid taking bottle 1 will rotate around its center so thatthe first mouth is raised and the bottom of the bottle is lowered, andthe heavy ball 2 in the liquid taking, bottle 1 will leave from, thefirst mouth of the bottle, and at this point the brine will flow intothrough the first mouth of the bottle and the low-density displacementliquid is displaced. When the height of the first mouth of the bottleexceeds the height of the bottom, of the bottle. the heavy ball 2 willroll onto the bottom of the bottle and the entire liquid taking bottle 1is filled with the brine.

The method may further comprise step S04, controlling the first mouth ofthe liquid taking bottle to face downward, and taking out the liquidtaking device.

In some embodiments, in step S04, after the entire liquid taking bottle1 is filled with the brine, the liquid taking device needs to be takenout. At this point, the liquid taking bottle 1 needs to be turned overagain, and then taken out. Therefore, the liquid taking rope 3 connectedto the first mouth needs to be slowly lowered. At this point, the firstmouth of the bottle will be lowered with the liquid taking rope 3 beinglowered. However, in order to ensure that the position of the liquidtaking bottle 1 remains unchanged, it is necessary to raise anotherliquid taking rope 3 connected to the bottom of the bottle at the samespeed when the first mouth of the bottle starts to descend, and at thatpoint the liquid taking bottle 1 will rotate around its center so thatthe first mouth of the bottle is lowered and the bottom of the bottle israised, and the heavy ball 2 in the liquid taking bottle 1 will leavefrom the bottom of the bottle. When the position of the first mouth ofthe bottle is lower than the position of the bottom of the bottle, theheavy ball 2 will roll into the first mouth and block the first mouth.When the liquid taking bottle 1 returns to its vertical state, the heavyball 2 will completely block the first mouth of the bottle, until theentire liquid taking bottle 1 is suspended again only by the liquidtaking rope 3 connected to the bottom of the bottle. When the liquidtaking bottle 1 is suspended by the liquid taking rope 3 connected tothe bottom of the bottle, the two liquid taking ropes 3 are raised atthe same speed so that the force applied to the liquid taking ropes 3remain unchanged until the liquid taking device is completely taken out.

As another embodiment of the present disclosure, what is different fromthe aforementioned embodiment is that the bottle body of the liquidtaking bottle 1 in this embodiment is made integrally. FIG. 4illustrates a schematic front structural view of the liquid takingdevice in this embodiment. The bottom of the bottle may comprise aball-filling hole and a ball-filling hole cap. The diameter of theball-filling hole is larger than the diameter of the heavy ball 2. Theheavy ball 2 can be put in through the ball-filling hole. Theball-filing hole cap is arranged on the ball-filling hole to prevent theheavy ball 2 from falling out.

The embodiments of the present specification provide a liquid takingdevice and a liquid taking method. Since the first mouth and the bottomof the liquid taking device are both connected with a liquid takingrope, the liquid taking device can be controlled to reach differentdepths under the ground by the action of two liquid taking ropes. Whenthe first mouth of the bottle is placed downwards, the, heavy ballblocks the first mouth under its own gravity to prevent liquid leakage.When the first mouth of the bottle is turned upwards under the action ofthe liquid taking ropes, the heavy ball falls into the bottom of thebottle so that the external liquid can flow into the liquid takingdevice, thereby achieving the, purpose of liquid taking. Through thesynergistic actions between the liquid taking ropes and the heavy ball,the brine deep under the ground can be taken out simply and effectively,which has a good practical utility.
